When two plane mirrors are inclined to each other at an angle of 100 degrees, the number of images formed can be calculated using the formula: ( n = \frac{360}{\theta} - 1 ), where ( \theta ) is the angle between the mirrors. In this case, ( n = \frac{360}{100} - 1 = 3.6 - 1 = 2.6 ). Since the number of images must be a whole number, we take the floor value, resulting in 2 images being formed. Thus, the two mirrors will create 2 distinct images.

When two plane mirrors are tilted at an angle of 60 degrees, there are 5 images will be formed.

When two plane mirrors are tilted at an angle of 72 degrees, six images are formed. The first two images are the direct reflections from each mirror, and the remaining four images come from the multiple reflections between the mirrors.
To find out how many images are formed when plane mirrors are tilted at an angle, use the formula N=360/a-1 , wherein N is the number of images formed and a is the given angle. So in this case, N=360/30-1, will result to N=11 images formed.

The answer depends on the angle between the mirrors. The distance between the mirrors does not, in theory, make any difference. If the angle between the mirrors is x degrees, then the theoretical number of images is (360/x)- 1 which is rounded down. In practice, minor defects in the mirrors, refraction, total internal refraction, absorptions, scattering etc will reduce the number of images.The answer depends on the angle between the mirrors.

To derive the formula for the number of images formed by two mirrors, first consider the angle between the mirrors, denoted as θ. The formula for the number of images (N) is given by ( N = \frac{360^\circ}{\theta} - 1 ) when the angle is less than 180 degrees. If the angle is greater than 180 degrees, the formula simplifies to ( N = \frac{360^\circ}{\theta} ). This accounts for the repeated reflections of the images created by the two mirrors.
